The steady march towards 4K on mobile devices continues, with Japan Display Inc (JDI) announcing the availability of its first 10.1-inch tablet display of 4K resolution.

JDI is now shipping samples of the new IPS LCD panel, which features a resolution of 3,840 x 2,160, qualifying it for the 4K moniker. The display maker actually calls this resolution “4K2K” or “ultra-high resolution”. At 10.1-inch, the panel will feature an amazing 438ppi pixel density, putting it on par with current generation smartphones.

The new panel is an evolution of the 12.2-inch 4K module that JDI introduced back in September, and is made using the low temperature polysilicon process (LTPS) that brings lower power consumption and a smaller thickness. According to JDI, the new panel consumes the same power as a less dense 2,560 x 1,600 panel built with amorphous silicon technology. More specifically, the 10.1-inch 4K panel will draw a total of 2180mW, with the backlight taken into account.

The world’s top maker of LCD panels, Japan Display Inc combines the production capacities of Japanese giants Sony, Hitachi, and Toshiba.

Sony is likely to be one of the main clients for the new 10.1-inch 4K LCD display, which seems a perfect fit for the third generation of the Xperia Z Tablet series. The current generation, the Xperia Z2 Tablet, features a Full HD (1920 x 1080) display, a step behind the current state of the art, the Quad HD (2560 x 1440) panel on Samsung’s Galaxy TabPRO 10.1 tablet.

While the debate rages on around the merits of 4K resolution on small displays, manufacturers are pushing forward with their plans to breach the 4K barrier on mobile devices. On smartphones, the current high-end standard is Quad HD (also known as 2K); the Oppo Find 7 is the first widely available smartphone to feature a Quad HD display, with LG and Samsung rumored to release their own soon. However, the benefits of going Quad HD may not be apparent to users, as our quick comparison demonstrates.

    Awesome. A Z3 Tablet with this high res will be amazing. The current Z2 Tablet isn’t high enough res for a 10″ device.

      The current Z2 tablet isnt high enough for a 10 inch device? It has more resolution than most TV’s and is still used closer to the face than TV’s.

      • M3D1T8R

        Correct. It’s used closer to the face, precicely why it needs to be higher res than a TV that’s maybe 8 feet away. My 5″ phone is 1080, my 7″ tablet is 1080, my 24″ monitor is 1080, and my 55″ plasma TV is 1080. It is the right resolution for all of them, given the difference in viewing distance.
        Would I be holding a 10″ tablet much further from my face than my Nexus 7? I doubt it. So it wouldn’t hurt for that much larger screen to be higher res, in that case. While 2160 (4K) does seems like overkill (I think 1440 would probably be adequate on a 10″), I’m all for innovation and seeing what the actual user experience is like.

        • Be realistic, man! In a couple of years, when a higher resolution is developed, you’ll be saying that 4K isn’t good enough. I have a Galaxy Note with a 720p display and is very good. I’m planning to move to both 1080p-display tablet and phone though. That’s because I want better resolution, but if I kept saying that no resolution is high enough, I might not buy any device ever.

            I have a 39″ UHD TV, 2K 10″ tablet, 1080p 7″ tablet and 5″ smartphone, how does that stop me wanting UHD in 7″, reading glasses cost $2.50.

          • FTR, “8K” devices already exist…

          • Jan Morrida

            You are right! When is it good enough?

      • MasterMuffin

        That means that it will look less sharp, because you’re using it closer to your face…

        • Mawly

          It has much bigger PPI.

    • Jan Morrida

      Most certainly is…

  • MasterMuffin

    And what GPU is going to handle that with next gen games :O

    • stucrmnx120fshwf

      In terms of display, I am getting an Amlogic S802 for $133 to drive my UHD TV in Android, a Tegra 4, with 72 cores can handle 4K, K1 has 192. But your right to get the best from a 4K in gaming you need hundreds of GPU cores. Those GPUs have to be running fast, such as 14nm, with lots of fast RAM, again 14 nm, which is best served by 64 bit processors, operating systems and core apps. For instance 4 GB of LPDDR4, to store lots of video 128 GB of flash. 64 bit systems will be coming Christmas, the chip makers have spent $40 billion on 14 nm. We’ve already seen Chinese making 128 GB and 2K phones, my 2K Nexus 10, only cost me $300. I look forward to 7″ UHD tablets, I downloaded 2 hours of HD video the other day in 2 minutes. 120 minutes of HD in 120 seconds, over copper line, FHD video comes in at just 0.8 GB.

      • Chris

        14nm is the fastest nm

        • stucrmnx120fshwf

          Yes we’re currently at 28nm, this will allow 5GHz 16 core, CPUs running cool.

          • Chris

            It’s just funny because nm (nanometer) is a size and you used it to refer to speed. I got what you were saying tho :P

    • deur

      Nvidia GeForce GTX 670

      • MasterMuffin

        That’s for poor. GTX Titan Tri-SLI :D

      • Sal

        But I don’t want a heatsink protrude on the back of my tablet..

        • stucrmnx120fshwf

          He he, lol, but at 14 nm, 5 GHz 16 core CPU, 1.5 GHz 600 GPUs would run cool enough, 4 GB LPGDDR6 RAM, 128 GB flash built in.

          • Jonathan TAM

            Give me a tablet with an 8K display, intel i7 Extreme, watercooling, 1tb ssd, 20000 mAH battery and GTX Titan Black 6GB 6-way sli. o.O

          • stucrmnx120fshwf

            Looks like your going to need, lithium doped carbon nano tubes, for the battery, a honeycomb of CPU/GPU, GDDR6 RAM, flash, optical interconnects. All 3D printed, with super low viscosity fluids, micro machine pumps, isolated into micro Faraday cages, but your singing to the choir, on that one bro, the more the merrier.

    • David Onter

      Snapdragon 805 has full 4k support :D

  • Brendon Brown


  • Tjaldid

    a 4K screen, 4GB Ram and a 64-bit processor along with a bigger battery and stylus support will make the Z3 A KILLER tablet

    • stucrmnx120fshwf

      I’m with you, only in my fantasy, it’s a Nexus 6, has LPGDDR6, 128 GB flash built in, 14 nm chips, running at 5 GHz, 16 cores.

  • wat

    Isn’t the Z2 1920×1200 not 1920×1080??

    • You’re right, it has been this display for two generations now. We were hoping for a 2560×1440 display ala Nexus 10 ala Galaxy TabPro 10.1, but alas, no dice.

  • Andreas

    Well, I’m hoping for the Sony Xperia Z4 Tablet early 2015, gimme gimme :D
